Missouri woman accused of poisoning husband with toxic plant charged with attempted murder

A Missouri woman accused of poisoning her husband has been charged with attempted murder, officials said Wednesday. 

The Jefferson County Police Department said in a statement that its officers investigated a call "involving allegations of intentional poisoning of a spouse" on Jan. 16. The victim told officers that he believed his unexplained illness was actually due to poisoning by his wife, identified by CBS affiliate KRCG as 37-year-old Sarah Scheffer. 

According to court documents reviewed by KRCG, the man said he was suspicious of his wife and thought she had been putting substances in his food and drinks for about six weeks. He experienced symptoms of fatigue, confusion, blurred vision, dry mouth and nausea.
